The Card Capital Shop Tournament begins soon, but Aichi is hesitant to play in it, even after making a new deck. However, when he learns that Kai will be in the tournament, Aichi decides to enter as well. But when he submits his entry application form, another Vanguard player, Osamu Kishida, places his application at nearly the same time as Aichi. Both of them want to enter, but there is only one open spot left in the tournament. To resolve this issue, Shin recommends to have Aichi and Osamu play against each other to see who gets the last entry spot.
